Hi there. I have been wanting to reinstall XP Professional on my PC however when I type the following in dos: f: cd i386 winnt I get an error stating: "An Internal error has occurred. Could not find a place for a swap file." I dont know what the problem is because if i place the cd into my other pc's and run setup via dos, the setup program works fine. Im not really sure on what i should do - use fdisk, delete C:, recreate it then attempt an install? The thing about that is when writing a floppy disc with windows 98 boot, i keep getting "Disc error in track x, head x. Address mark not found." My HDD is 250 gig, partitioned as follows: C: 20GB D: 19.9GB E: 99.9GB F: 92.8GB I am using 15 gig on C: (OS, apps and files) and about 20 gig on E:, backups. I also have 1gig of ram if it makes any difference? Thanks for reading and thanks in advance for any support! Nad
